BSH111BKR

Nexperia · MOSFETs · SOT-23

BSH111BKR from Nexperia, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate terminal of the MOSFET; the gate-source voltage is limited to -10 V to 10 V (Table 5).
2 S passive Source terminal of the MOSFET; the source current is limited to 200 mA at Tamb = 25 °C (Table 5).
3 D passive Drain terminal of the MOSFET; the drain-source voltage is limited to 55 V and the drain current to 210 mA at Tamb = 25 °C with VGS = 4.5 V (Table 5).
